Understanding the fundamentals of events
Event-driven architecture revolves around events. Understanding the fundamentals of events is crucial for designing and implementing robust event-driven architecture systems. This section explores events’ core aspects, characteristics, types, and how they fit into the overall architecture.
What is an event?
An event is a significant change in state or occurrence within a system that interests other system components. It represents an action or condition triggering a response or processing by other system parts. Events are fundamental communication units in event-driven architecture, allowing systems to react to changes in real time.
Characteristics of events
Events have characteristics that define their nature and how they are handled within an event-driven architecture system:
- Immutable: Events must be immutable, meaning they cannot be altered after publication. This ensures consistency across distributed systems...
